Abstract :
A six-stage successive detection logarithmic amplifier (SDLA) is described in which each stage is a GaAs monolithic microwave integrated circuit (MMIC) incorporating RF amplification, detection, and a novel video summation technique, using standard 0.5 mu m process FETs and Schottky diodes. The circuit has a dynamic range of 80 dB at 3.8 GHz with linearity of +or-1 dB and power dissipation of 4.0 W.<>
